Then users need to realize ffmpeg 8.0.1 ( has been in SF since 7.0.0.7 back to 2026-01-16.
And if that is what is causing this, users have much work ahead of them fixing files.
Indeed we need to hear from @Wilson.Wang on this.
Right now I know I don’t feel like going back to files from late January to see if the play or not.
So far videos play with Plex, but I doubt I watched all videos I have downloaded since late Janurary.
But if they don’t work I might try running them through handbrake and if no success then look to “avidemux” .
Also is it using ffmpeg for mp4 and mkv or just mp4?
And then it should inot affect mkv with the mkvtoolnix option?
So that option could maybe be used to get around it.
But if users feel fine going back to ffmpeg 7.11, and replacing it in the SF folder, and it’s working, then they should do what is working,
This should effect me as I get videos from:
Fandango
Roku
Netflix
I guess though mostly Netflix.
Also at same time I change between mp4 and mkv so don’t know.
